Webinar: On-Road Emission Studies

Postby kathyerickson on Fri Aug 13, 2010 8:31 am

On August 19th, Jason Johnson, a formal post-graduate research student of Professor David Kittleson at the University of Minnesoty Center of Diesel Research will be giving a webinar titled On-Road Emission Studies: Design and Results. If you are interested in mobile source emissions you can register for the webinar at http://www.tsi.com/webinars. Below are more details about the webinar and the speaker.

Mobile sources typically generate large amounts of ultra-fine particles (UFPs), and the environmental implications and health effects of these nano-sized UFPs are a growing concern. While these emissions may be studied in the laboratory, the sheer complexity of their interactions with the world and with each other make real-world and on-road measurements necessary for truly understanding mobile source aerosols.

This presentation will discuss the necessary tools, methods, and unique approaches to making on-road aerosol measurements. Both stationary and vehicle-based measurements will be discussed, with a focus on the wide variety of vehicle-based measurements (continuous sampling, “chase tests”, etc.). Examples of these methods, drawn from published studies, will also be presented, with special emphasis on the work of the University of Minnesota’s Mobile Emissions Laboratory (MEL).

About the Presenter:
Jason Johnson is a mechanical engineer and aerosol physicist, specializing in aerosol instrumentation and the study of environmental nanoparticles. He has conducted research and co-authored a number of papers on a wide variety of topics including combustion aerosols, methods for on-board mobile source pollutant measurements, biofuels, the effect of diesel fuel sulfur levels on real-world nanoparticles, and nanoparticle toxicology. He is also an experienced designer of liquid and exhaust filtration products and is an expert in computational and statistical methods and the design of experiments. Mr. Johnson has a B.S. in Physics and an M.S. in Mechanical Engineering from the University of Minnesota, Twin Cities.
